E. H. PEABODY COMBINATION GAS AND OIL BURNER Filed Feb. 28-, 1925 ATTORNEY Patented Jan. 14, 1936 UNITED STATES PATENT OFFICE-f ERNEST H. PEABODY, OF PELHAM MANOR, NEW YORK, ASSIGN OR TO PEAIBODY ENGI- NEERING CORPORATION, OF NEW YORK, N. Y, A CORPORATION OF NEW YORK COMBINATION GAS AND OIL BURNER Application filed February 28, 1925.

My invention relates to combination gas and oil burners, especially to that type for burning combustible gases, and liquids, more fully described in an application filed by me simultaneously herewith, Serial Number 12,301, filed February 28, 1925' and has for its object to provide a means for mounting the airregister and atomizer so that thegas chamber is more easily accessible.

A further object is to provide a simple means for supplying air through the gas burner, while burning liquid combustibles, in suificient quantity to prevent warping and distortion of the gas burner.

The foregoing and other features of my invention will now be described in connection with the accompanying drawing forming part of this specification in which I have represented my device in its preferred form, after which I shall point out in the claims those features which I believe to be new and of my own invention.

In the drawings Figure l is a side elevation of my device attached to a furnace front.

Figure 2 is a front view, with the details of the various connections omitted.

Figure 3 is a section 33, Figure 2.

Figure 4 is an enlarged cross sectional detail of the gas chamber showing the c0nnection to outer air.

In the carrying out of my invention I employ an air register 1, adapted to support a standard atomizer 2, a gas chamber 3 provided with a circumferential slot 4 adapted to supply gas to a combustion chamber 5. The gas chamber is'adapted to fit an opening 6 in a furnace front 7 and be secured thereto by means of stud bolts 8. The gas chamber is composed of two parts (10 and 13) forming an annular chamber provided with a gas inlet and circumferential slot 4 leading into the combustion chamber, all of which is more fully described in the application above referred to.

The part 10 of the gas chamber is fastened to the furnace front and the part 13 is secured to the part 10 by the bolts 16. The part 10 is provided with openings 17 which are closed by the plugs 18 when gas Serial No. 12,302.

' The part 13 of the gas chamber is provided with a seat 20 adapted to receive and center the male member 21 of the air register 1.

The air register is of any well-known type provided with segmental doors 22 pivotally mounted at 23. The front plate 24 of the air register is provided with extensions 27, carrying means 28 for pivoting the door to the bracket or support 29 which may be bolted either to the gas ring 10 by means of bolts 8 or to the furnace front "or both, as shown, to permit the air register to swing away from its seat formed in the wall of the gas chamber. 4

With this arrangement the air register.

may be swung away from the gas chamber permitting easy access to all operating parts. When the air register is swung towards the furnace front the part 21 contacts with the circular seat 20 of the gas chamber-and thereby centers the unit in operating position. I

In the foregoing disclosure I have described and illustrated my apparatus as designed for an enclosed housing surrounding the air register into which air for combustion is delivered under pressure but it may be adapted for use'with a furnace where natural draft is employed and which therefore requires no housing as will be readily understood.

I wish it distinctly understood that my combination gas and oil burner herein described vand illustrated is in the form in which I desire to construct it and that changes or variations may be made as may be convenient or desirable without departing from the salient features of my inventlon an 35 adapted to be fitted. to a I therefore intend the following claims to cover such modifications as naturally fall within the lines of invention. T

1.A burner comprising a fuel chamber adapted to fit an opening in a furnace wall, means for supplying fuel to'said chamber and for discharging 1t therefrom, said chamher having a seat and an air register mounted to move to and from said seat.

2. A burner comprising a fuel chamber adapted to fit an opening in a furnace wall means for supplying fuel to said chamber and I for discharging it therefrom, said chamber havin a seat and an air register hinged to said amber swing to and from said seat.

3. A burner comprising a fuel chamber adapted to fit an opening in a furnace wall, means for supplying fuel to said chamber and for discharging it therefrom, said chamber having a seat an air register mounted to move. to and from said seat, and a liquid fuel atomizer carried by said air register. 7 I 1 a5 4. A burner comprising a fuel chamber adapted to flt an opening in a furnace wall, means for supplying fuel to said chamber and for discharging it therefrom, said chamber having a seat, an air register mounted to move to and from said seat, and

a liquid fuel atomizer carried by said register and mounted to discharge its fuel a j cent said chamber when in operation.

,5. A burner comprisin a fuel chamber gurnace wall adjacent an opening therein, said chamber having a circumferential outlet, an air register. mounted to move toand from -a seat upon said chamber and a liquid fuel-atomizer carried by said ir register and mounted to dis- ,charge its fuel ad acent said chamber when in operation.

In testimony whereof I aflix my si ature.
